If any electrolyte gets into your
eyes, flush your eyes with
clean water for at least 15 min-
utes and get immediate medi-
cal attention. If possible, con-
tinue to apply water with a
sponge or cloth until medical
attention is received.
If electrolyte gets on your skin,
thoroughly wash the contacted
area.
If you feel a pain or a burning
sensation, get medical atten-
tion immediately.
Wear eye protection when
charging or working near a bat-
tery.
Always provide ventilation
when working in an enclosed
space.WARNING:
!
WARNING:Always read the following in-
structions carefully when han-
dling a battery.
Keep lighted cigarettes and all
other flames or sparks away
from the battery.
Hydrogen, which is a highly
combustible gas, is always
present in battery cells and
may explode if ignited.
Keep batteries out of the reach
of children because batteries
contain highly corrosive SUL-
FURIC ACID. Do not allow bat-
tery acid to contact your skin,
eyes, clothing or paint finish.
o When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak, resulting in
personal injury. Lift with a battery
carrier or with your hands on opposite
corners.
o Never attempt to charge the battery
when the battery cables are con-
nected.
o The electrical ignition system works
with high voltage.
Never touch these components with
the engine running or the ignition
switched on.

POWER STEERING FLUID
LEVELG230A01TG-AAT
G230A01TG
The power steering fluid level should be
checked regularly. To check the power
steering fluid level, be sure the engine is
"OFF", then check to make certain that the
power steering fluid level is between the
"MAX" and "MIN" level markings on the
fluid reservoir.

G220A01A-AAT
WARNING:
The cooling fan is controlled by engine
coolant temperature and may some-
times operate even when the engine is
not running. Use extreme caution when
working near the blades of the cooling
fan, so that you are not injured by a
rotating fan blade. As the engine coolant
temperature decreases the fan will au-
tomatically shut off. This is a normal
condition.G220B01NF-GATChecking Engine Cooling FanThe engine cooling fan should come on
automatically if the engine coolant tem-
perature is high or whenever the air con-
ditioning is in operation.
G240A01A-AATPOWER STEERING HOSESIt is suggested that you check the power
steering hose connections for fluid leak-
age at those intervals specified in the ve-
hicle maintenance schedule in Section 5.
The power steering hoses should be re-
placed if there is severe surface cracking,
pulling, scuffing or worn spots. Deteriora-
tion of the hose could cause premature
failure.NOTE:Grinding noise from the power steering
pump may be heard immediately after
the engine is started in extremely cold
conditions (below - 4°F). If the noise stops
during warm up, there is no abnormal
function in the system. It is due to a
power steering fluid characteristic in
extremely cold conditions.
Recommended FluidUse PSF-4 type fluidNOTE:Do not start the engine when the power
steering oil reservoir is empty.

WARNING:
o When removing/replacing halogen
bulbs, always handle the metal body
of the bulb, not the glass.
o This halogen bulb contains gas under
pressure and if impacted could shat-
ter, resulting in flying fragments. Al-
ways wear eye protection when ser-
vicing the bulb. Protect the bulb against
abrasions or scratches and against
liquids when lighted. Turn the bulb on
only when installing in a headlight.
Replace the headlight if damaged or
cracked. Keep the bulb out of the
reach of children and dispose of the
used bulb with care.

EMISSION CONTROL SYSTEMS2
EMISSION CONTROL
SYSTEMS
H010B01A-AAT1. Crankcase Emission Control Sys-
temThe positive crankcase ventilation system
is employed to prevent air pollution caused
by blow-by gases being emitted from the
crankcase. This system supplies fresh fil-
tered air to the crankcase through the air
intake hose. Inside the crankcase, the fresh
air mixes with blow-by gases, which then
pass through the PCV valve into the induc-
tion system.
CanisterFuel vapors generated inside the fuel tank
are absorbed and stored in the onboard
canister. When the engine is running, the
fuel vapors absorbed in the canister are
drawn into the surge tank through the
purge control solenoid valve.Purge Control Solenoid Valve (PCSV)The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant tempera-
ture is low during idling, the PCSV closes
so that evaporated fuel is not taken into the
engine. After the engine warms-up during
ordinary driving, the PCSV opens to intro-
duce evaporated fuel to the engine.
H010A01NF-AATYour Hyundai is equipped with an emis-
sion control system to meet all emission
regulations.
There are three emission control systems
which are as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of the
emission control systems, it is recom-
mended that you have your car inspected
and maintained by an authorized Hyundai
dealer in accordance with the maintenance
schedule in this manual.
Caution for the Inspection and Mainte-
nance Test (With Electronic Stability
Control (ESC) system)
o To prevent the vehicle from misfiring
during dynamometer testing, turn the
Electronic Stability Control (ESC) sys-
tem off by pressing the ESC switch.
o After dynamometer testing is com-
pleted, turn the ESC system back on
by pressing the ESC switch again.
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refuel-
ing Vapor Recovery) SystemThe Evaporative Emission Control Sys-
tem is designed to prevent fuel vapors from
escaping into the atmosphere.
(The ORVR system is designed to allow
the vapors from the fuel tank to be loaded
into a canister while refueling at the gas
station, preventing the escape of fuel va-
pors into the atmosphere.)

CATALYTIC CONVERTERH020A03A-AAT(If Installed)Hyundai vehicle is equipped with a mono-
lith type three-way catalytic converter to
reduce the carbon monoxide, hydrocar-
bons and nitrogen oxides contained in the
exhaust gas. Exhaust gases passing
through the catalytic converter cause it to
operate at a very high temperature. The
introduction of large amounts of unburned
gasoline into the exhaust may cause the
catalytic converter to overheat and create
a fire hazard. This risk may be reduced by
observing the following:Catalytic Converter
H010D02A-AAT3. Exhaust Emission Control
SystemThe Exhaust Emission Control System is a
highly effective system which controls ex-
haust emissions while maintaining good
vehicle performance.
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic
converter temperatures can result
from improper operation of the elec-
trical, ignition or multiport electronic
fuel injection.
o If your engine stalls, pings, knocks, or
is hard to start, have your Hyundai
dealer inspect and repair the problem
as soon as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause
the engine to misfire and result in
damage to the catalytic converter.
o Avoid idling the engine for periods
longer than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause
the catalytic converter to overheat
and create a fire hazard.

PROPOSITION 65 WARNING:
Engine exhaust and a wide variety of
automobile components and parts, in-
cluding components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of Califor-
nia to cause cancer and birth defects
and reproductive harm. In addition, cer-
tain fluids contained in vehicles and
certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
